Agis Software v. AT&T: Consent Judgment After 766 Days in E.D. Texas
Agis Software Development LLC brought a six-patent infringement campaign against AT&T Inc. and its affiliates in the Eastern District of Texas, asserting mobile communication and ad hoc network patents covering cellular and PDA systems. The case closed via consent judgment after 766 days — a resolution that binds both parties under court authority without a merits ruling.
Six mobile patents, one telecom giant, a negotiated court-entered resolution
Filed on 29 January 2021 in the Eastern District of Texas, Agis Software Development LLC — a patent assertion entity represented by Fabricant LLP — sued AT&T Inc., AT&T Services Inc., and AT&T Mobility LLC for infringement of six US patents covering cellular phone and PDA communication systems, ad hoc digital and voice networks, and related mobile location technologies. The asserted patents span application dates from the mid-2000s through the early 2010s, suggesting a mature but actively monetised portfolio.
The case terminated on 6 March 2023 by consent judgment — a court-entered judgment reflecting terms agreed between the parties. Although the docket reflects a Notice of Voluntary Dismissal Without Prejudice under Rule 41(a)(1)(A)(i), the authoritative Basis of Termination is Consent Judgment, indicating the parties reached a structured agreed resolution that was formally adopted by the court. Such instruments typically encode licensing terms, covenants not to sue, or other commercial arrangements not visible in the public record.
The 766-day duration is consistent with a case that progressed through at least initial claim construction skirmishing before the parties negotiated an exit. Agis Software has filed numerous related suits against other major mobile carriers, suggesting a systematic licensing campaign; AT&T's resolution here may reflect a desire to avoid the risk and cost of full merits adjudication. The specific financial or licensing terms of the consent judgment remain confidential and cannot be confirmed from the public record.

US9408055B2 — mobile cellular and ad hoc network communication systems
Any company developing or commercialising cellular communication platforms, mobile PDA systems, ad hoc voice or data networks, or group messaging features for smartphones should treat this portfolio as a live FTO concern. Agis Software has demonstrated a willingness to litigate through 766-day proceedings against a defendant the size of AT&T. Smaller carriers, MVNOs, enterprise mobile software vendors, and OEMs face comparable exposure with fewer resources to absorb litigation costs.
Official order — verbatim text
The court's order accepts a Rule 41(a)(1)(A)(i) notice of voluntary dismissal without prejudice filed by Agis Software, directing the clerk to close the case. However, the authoritative Basis of Termination is Consent Judgment, indicating the parties reached a binding agreed resolution adopted by the court. No validity finding, no infringement determination, and no claim construction ruling issued — the six asserted patents exit the proceeding legally unchallenged on the merits, leaving enforcement options intact against third parties.
Consent judgment: what the agreed resolution means for both parties
What a consent judgment means in patent litigation
A consent judgment is a binding, court-entered judgment on terms negotiated and agreed by the parties. Unlike a unilateral dismissal, the court actively endorses the resolution, giving it the full force of a judicial order. Either party can return to court to enforce its terms. Here, even though the underlying procedural vehicle was a Rule 41 notice, the authoritative termination basis is Consent Judgment — the court's acceptance creates a judicially enforceable final resolution.
Court-entered, binding, enforceableAgis Software: controlled exit with enforcement leverage preserved
For Agis Software, a consent judgment typically signals that value was extracted — whether through a licensing fee, a covenant, or commercial terms — without the risk of an adverse merits ruling that could weaken the portfolio. The six asserted patents remain formally unchallenged on the merits, preserving their enforceability against other defendants. Agis's continued litigation activity against other carriers suggests this resolution was a strategic monetisation step, not a capitulation.
Portfolio enforceability preservedAT&T: litigation risk retired, terms undisclosed
AT&T and its affiliates — AT&T Services Inc. and AT&T Mobility LLC — secured an end to this specific proceeding without a public finding of infringement or validity. A consent judgment commonly includes a licence or covenant not to sue, which would give AT&T commercial certainty going forward. The confidential nature of the terms means the precise scope of any licence granted cannot be confirmed, but the resolution eliminates the immediate litigation exposure across all three AT&T entities named.
Litigation exposure eliminatedMobile carrier IP risk: Agis's portfolio remains a live enforcement threat
Because no merits ruling issued, the six Agis patents emerge from this case with their validity and infringement positions untested. Other carriers and mobile platform vendors operating in the cellular communication, ad hoc networking, and location-based services space face continued exposure. The consent judgment against AT&T may set a benchmark valuation for licensing negotiations with remaining targets. Companies in adjacent technology areas — push-to-talk, device management, mobile group communications — should assess their FTO position against this portfolio.

R&D signals in the mobile communication and ad hoc network space
Forward-looking patent and innovation intelligence derived from Agis Software's mobile portfolio and AT&T's competitive IP posture in cellular and ad hoc network technology.
Agis Software's mobile patent family — scope and continuation activity
Agis Software has built a portfolio through successive continuation filings from foundational mobile communication applications dating to the mid-2000s. Monitoring new continuations, divisionals, or continuation-in-part applications filed from the same priority chains as US9408055B2 and its co-asserted patents reveals where Agis is extending coverage — and which product categories may face future assertion risk.
Continuation filings to watchFiling trends in ad hoc mobile network and group communication patents
The ad hoc network and secure group communication space — encompassing push-to-talk, device mesh networking, and location-aware group messaging — has seen sustained filing activity from both established carriers and start-ups. Understanding claim density and white-space areas in this domain helps R&D teams design around existing coverage and identify filing opportunities before competitors close the landscape.
Active filing domainAT&T's defensive patent position in mobile network technology
AT&T holds a substantial offensive and defensive patent portfolio in cellular network infrastructure, mobile software, and device communication protocols. Analysing AT&T's own filing activity in the ad hoc networking and group communication sub-domains — particularly patents that could be used as cross-licensing leverage or invalidity prior art — informs a full competitive intelligence picture for this technology space.
Carrier defensive portfolioAdjacent R&D opportunities near Agis's asserted patent claims
The Agis patents focus on system-level and method-level claims for cellular and PDA communication with ad hoc network formation. Adjacent areas — including device-to-device 5G sidelink communication, encrypted mesh networking for IoT, and AI-driven dynamic group formation — show thinner patent coverage and represent potential white-space opportunities for R&D teams seeking freedom to operate while building next-generation mobile network features.

What this case signals for the mobile communications IP landscape
Agis Software's E.D. Texas campaign against major carriers signals sustained monetisation pressure on mobile network and ad hoc communication patents.
E.D. Texas consent judgments signal active licensing campaigns — monitor related filings
When a patent assertion entity like Agis Software resolves with a major defendant via consent judgment rather than a merits ruling, it typically indicates an ongoing, multi-defendant licensing programme. Other mobile carriers and device manufacturers should track Agis's docket activity and assess whether the same six patents — or related family members — are being asserted elsewhere.
Six unlitigated-to-verdict patents create residual FTO risk for the mobile sector
None of the six asserted patents received a validity or infringement determination. For companies building cellular communication systems, ad hoc network platforms, or mobile PDA services, these patents remain live obstacles. An FTO search against US9408055B2, US9445251B2, US9467838B2, US9749829B2, US7630724B2, and US7031728B2 is advisable before product launch or M&A diligence in this space.
Agis v AT&T — key questions answered
The case closed by consent judgment on 6 March 2023, after 766 days. Although the docket reflects a Rule 41(a)(1)(A)(i) voluntary dismissal without prejudice notice, the authoritative Basis of Termination is Consent Judgment — a binding, court-entered resolution on agreed terms. No merits ruling on infringement or validity issued.
Agis asserted six US patents: US9408055B2, US9445251B2, US9467838B2, US9749829B2, US7630724B2, and US7031728B2. The patents cover cellular phone and PDA communication systems, methods of providing such systems, and ad hoc password-protected digital and voice network methods. All six patents exited the proceeding without a validity or infringement determination.
No. A consent judgment reflects a negotiated resolution adopted by the court — it does not constitute a finding of infringement or invalidity. The specific terms, including any licensing arrangement or covenant not to sue, are not disclosed in the public record. AT&T neither admitted nor was found liable for infringement of the six asserted patents.
The six asserted patents remain valid and enforceable — no court narrowed their claims or found them invalid. Other carriers, MVNOs, enterprise mobile software vendors, and OEMs operating in cellular communication, ad hoc networking, or group messaging face potential exposure. The AT&T resolution may set an implicit benchmark for licensing negotiations, and Agis's broader litigation campaign suggests further enforcement activity is consistent with its business model.
The Eastern District of Texas is a historically plaintiff-friendly venue for patent assertion, offering predictable scheduling, experienced patent juries, and procedural rules that have attracted patent assertion entities for decades. Agis Software has filed multiple actions in E.D. Texas against major technology and carrier defendants, suggesting a deliberate venue strategy as part of a systematic patent monetisation programme.
